一句句改吧：That is first reading a English book for me
用It 句型更加简洁通顺 It is my first time to read an english book.
Although my English not good, but i feel very expective.
这一句有两个很大的错误，首先是be动词的遗漏，句子缺少谓语，其次，英语的关联词只用一个就可以表达“尽管、但是”之意，在前面用了although之后后面就不用再写上but了最后一个名词拼写错误
Although my English is not good,I feel very expectative（其实不太清楚你用这个词是要表达什么意思，词意本是 预期中的 之意）.
For now, someone must be want to know how can I understand all of details. 同样是be动词的使用问题，这一句中，want已经是谓语动词了，用上be动词是错误的，直接用情态动词must来表达“一定'就可。此外，must be句型只能接形容词，例如，you must be very happy.你一定很开心吧。诸如此类
For now,someone must want to know how san I understand all the details.
Let is me tell you要说“让我来告诉你”直接用let me tell you就好，祈使句不要用be动词
I can get it 1/3, I find dictionary get it 1/3, and I guess 1/3. So, I can understand this book.
.....这几句是典型的chiglish，完全是按照中文语法英文单词组合的中国式英语，帮你改成下面这样了
I can get 1/3 of it,I look up to a dictionary and get another 1/3,then I get the last 1/3 by guessing,so I can understand this book.
This book about business and life.(又丢了be动词） Trump describe（第三人称单数要加s） his business and life and give people some inspires and passions.（inspire 和passion 均为不可数名词，不加s） That is my need.
this book is about business and life.Trump describes his business an life and offer people inspiration and passion which is what I need.（这里用了个宾语从句让句子更简练一些，offer是高级词汇，当然使用give也没有错）
I was reading that is book three days ago.这里是一般过去时的使用错误，正确的应为I read that book three days ago.
I will struggle to lend,（？？lend “借入” 你是想表达结束它的意思吗？I trust myself, I need self-fulfimeng.（这里应该用名词，需要。。。东西）
I will struggle to end it, I trust myself, I need self-fulfilments.
